pydoe 0.3

Design of experiments for Python

The pyDOE package is designed to help the scientist, engineer, statistician, etc., to construct appropriate experimental designs.

Capabilities

The package currently includes functions for creating designs for any number of factors:

• Factorial Designs

  1. General Full-Factorial (fullfact)

  2. 2-level Full-Factorial (ff2n)

  3. 2-level Fractional Factorial (fracfact)

  4. Plackett-Burman (pbdesign)

• Response-Surface Designs

  1. Box-Behnken (bbdesign)

  2. Central-Composite (ccdesign)

• Randomized Designs

  1. Latin-Hypercube (lhs)

See the package homepage for details on usage and other notes

What’s New

In this release, the Plackett-Burman constructor has been simplified to require only the number of factors: pbdesign(n). The design is now able to grow as large as necessary to accomodate any number of factors.

Also, the factorial (ff2n, fracfact, and pbdesign) designs have all been standardized (except for fullfact, which needs the flexibility) to have coded levels -1 and 1 for the low and high levels.

Requirements

• NumPy

• SciPy

Installation and download

See the package homepage for helpful hints relating to downloading and installing pyDOE.

Source Code

The latest, bleeding-edge but working code and documentation source are available on GitHub.
